CYLINDER-LUBRICATOR.

Specification of Letters Patent.

' Patented Aug. 22, 1905.

Application filed December 31,1904. Serial No. 239,169.

To all 1072,0711, it may concern:

Be it known that I, HARRY G. ELMORE, a citizen of the United States,residing at Spencer, in the county of Rowan and State of North Carolina,have invented certain new and useful Improvements in(Jylinder-Lubricators; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to lubricators for steam-engine and othercylinders, has especial reference to the lubrication oflocomotive-engine and other cylinders in whichthe lubricant is suppliedunder pressure of steam from the boiler, and consists in certainimprovements in construction whereby the supply of oil in the reservoirmaybe replenished while the lubricator is at work and WithoutWithdrawing the water therefrom.

The invention will be fully disclosed in the following specification andclaims.

In the accompanying drawings, which form part of this specification,Figure 1 represents a vertical longitudinal section, partly in sideelevation, of a lubricator embodying my invention on line 1 1, Fig. 2;Fig. 2, a vertical transverse section, partly in side elevation, on line2 2, Fig. 1; and Fig. 3, a plan top view.

In the practical operation of this class of lubricators it frequentlyoccurs that the oil in the reservoir has been consumed when the enginehas nearly reached the end of its run or trip, and to recharge thelubricator by drawing off the water and furnishing a fresh supply ofoil, then admitting steam to the reservoir and allowing it to condense,and then again admitting steam to the reservoir requires time andnecessitates the stopping of the train while this renewel of oil isbeing eflected, or that the engine and other cylinders must be runwithout a lubricant, which is very injurious and even destructive to thepistons, valves, and the cylinders. To remedy this serious defect, Ihave provided means for refilling or resupplying the lubricator with oilwhile the lubricator is at work or without interruption of its work bymeans which will be hereinafter fully disclosed.

Reference being had to the drawings and the designating charactersthereon, 1 indicates the body or reservoir of the lubricator, 2 thecondenser, provided with vertical tubes 3 4 5, communicating,respectively, with passages 6 7 8, leading to chambers 9 10 11,controlled by valves 12, 13, and 14, 12 and 14 controlling the supply oflubricant to the cylinders of a locomotive-engine and 13 the supply tothe air pump cylinders, 15 15 hand-oilers, 15 the feed-pipe in thereservoir 16 the filling-plug for the reservoir, 17 the steam-supplypipe, 18 the water-valve, 18 and 18 pipes for supplying water ofcondensation from the condenser to the oil-reservoir, 19observationglasses, 2O sight-feed drain-valve, 22 the waste-valve, 23the wastepipe for cleaning the reservoir, 12 and 13 the oil-pipesleading to the cylinders on opposite sides of the locomotive, and 14 theoilfeed pipe leading to the engine-cylinder of the air-pump, all ofwhich parts and their operation are well known to those skilled in theart to which my invention appertains, form no part of my invention,andtherefore require no further elucidation.

The reservoir 1 is separated into an upper and a lower chamber 24 and 25by a transverse and longitudinal partition 26, and the lower chamber isprovided with a supplemental filling-plug 27 for supplying oil to thelubricator while it is at work. In the partition 26 is a passage oropening 27, from the upper side of which extends a pipe 28, and on theunder side of the passage is a valve-seat 29, controlled by a valve 30,whose stem 31 extends through the wall of the body of the lubricator. 32is a like opening or passage in the partition, from which a pipe 33extends downward near to the bottom of the reservoir, and said passageis controlled by a valve 34, whose stem 35 also extends through the Wallof the body.

The lower end of pipe 33 extends near the bottom of chamber 25 toreceive Water under pressure of steam from chamber 24 and conducts it tothe lower chamber 25, near the bottom thereof, to force the oil upthrough pipe 28 into chamber 24. The valves 30 and 34 are closed, thewaste-valve 22 opened and the plug 27 removed, and waste-valve 22 againclosed. Oil is then supplied to the chamber 25, the plug 27 returned,the valve 34 opened slightly at first to allow Water under pressure ofsteam to enter bottom of chamber 25 and float or raise the oil to thetop of said chamber. The valve 30 is then opened,

when oil will pass through pipe 28 into chamber 24 under pressure ofwater and steam admitted through valve 34 and pipe 33 from the condenser2. The water and steam supplied through Valve 34 and pipe 33 flows fromthe condenser 2 through pipe 18, discharged near the bottom of chamber24, and is controlled by valve 18.

Having thus fully described my invention, what I claim is- 1. Alubricator provided with acondenser, a reservoir provided with an upperand a lower oil-chamber and having a transverse partition provided withmeans forming communication between said chambers, valves forcontrolling said means of communication, means for supplying water ofcondensation to the reservoir. and means for supplying steam thereto.

2. A lubricator provided with a condenser, a reservoir provided withan-upper and a lower oil-chamber and having a transverse partition,pipes extending from saidpartition into both of said chambers, valvesfor controlling said pipes, means for supplying wa- HARRY G. ELMORE.
